New in 1.1.0

Auto Discovery Support for Azure

Application Connector (AC) 1.1.0 now supports auto discovery and publish for Microsoft Azure. This feature applies appropriate Azure authentication when the proxy is in an Azure environment.

Enhanced Auto Discovery and Cloud Provider Authentication Troubleshooting

This release includes these enhancements to improve Proxy cloud diagnostics:

  • The Proxy provides a verbose and specific response when posting a cloud node fails.
  • For each resource (Service Center or Cloud Server), the Proxy user interface (UI)/API now enables you to ping the resource to determine if network connectivity exists from the Proxy to the resource.
  • The NODE DISCOVERY heading on the Proxy UI now displays whether the authorization is successful or the error returned by the cloud vendor during authorization if authorization was unsuccessful. Additionally, the Cloud vendor (AWS, Azure, Private) is displayed next to the Authorization Status. This information is also available using the API.

Enhanced Proxy/Service Center Connection Feedback

1.1.0 provides improved feedback when the Proxy fails to establish a connection to a Service Center.

Proxy Reconnection Frequency Enhancement

This release now includes a feature that changes the frequency that a Proxy attempts to reconnect to a Service Center upon loss of connection. The frequencies are:

  • 10-10 minutes, with a reconnection attempt made every second
  • 10 minutes to 60 minutes, with a reconnection attempt made every 30 seconds
  • 60+ minutes, with a reconnection attempt made every 60 seconds

AWS Assume Role/Agent Mode

In 1.1.0, AC Proxy supports the AWS Assume Role, which eliminates the need to store credentials file in the system. To use this feature, you create a role that has an access policy with varying degrees of permission level. F5 recommends that you use the AmazonEC2ReadOnlyAccess policy, which allows only read access to EC2 resources. To use this role, attach the role to the EC2 instance that hosts the Proxy. That instance will then have the EC2 role with read only access.

Cookies Persistence Enhancements

AC versions 1.0.0-1.1.0 do not support native BIG-IP software persistence; therefore it uses a persistence iRule to add persistence to any virtual servers requiring it. The persistence iRule client_cookie_persistence.tcl is now upgraded with a more efficient syntax. The Service Center iApp for versions 1.0.0-1.1.0 automatically add the persistence iRule to any virtual server selected as an application virtual server.

Enhanced Add Virtual Server Confirmation

In 1.1.0, the Service Center UI is enhanced to provide more specific feedback to a user regarding which virtual servers are being selected. Now when you select an App or Proxy virtual server and save it, a a message displays a list of selected virtual servers and asks you to confirm your selection.

Proxy and Service Center Help

This release now includes a Help page for the Service Center and Proxy.

Proxy Bind IP Address Option

1.1.0 now supports the use of the BIND IP docker environment variable (-b). This variable enables you to specify the IP address to which the Proxy should bind. This affects traffic from the Proxy to cloud servers and Service Centers, in addition to admin traffic.

Fixes, behavior changes, and known issues
